TYPE-WRlTlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 472,042, dated April 5, 1892.

Application filed October 9, 1890.

T (oZZ whom it may concern.-

Be it known that 1, JAMES F. FRANKEY, of Dodge City, in the county of Ford and State of Kansas, have invented certain new and useful Improvements in Type-\Vriting Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this o specification, and to the figures and letters of reference marked thereon.

The present invention relates to that class of typewriters in which the printing mechanism, consisting of type mounted on the ends 50f movable type-bars, is located below the platen, the impressions being made on the under side of the platensuoh, for instance, as described in my application, Serial No. 338,550, filed January 30,1890; and it has for 0 its objects to provide a simple and efficient mechanism for permitting the exposure of the printing-point and the inspection of the writing being done, further objects being to provide an improved ink-ribbon holding and 5 feeding mechanism and mechanism for returning the carriage and automatically feeding the paper forward and various improved mechanical details of construction to be hereinafter described. 0 The invention consists in certain novel details of construction and combinations and arrangements of parts, to be hereinafter described, and pointed out in the claims at the end of this specification.

In the accompanying drawings, Figure 1 is a side elevation of a type-writer constructed in accordance with the present invention, duplicate and well-known parts being omitted for the sake of clearness and the ink-ribbon a devices shown only in outline. Fig. 2 is a rear elevation of the machine. Fig. 3 is an enlarged end elevation of the carriage alone, with ink ribbon holder removed and the platen thrown up.

Fig. 25 is a detail of one of the bearings for the supplemental frame and the platen-pivot.

Like letters and numerals of reference in the several figures indicate the same parts.

The main frame A of the machine may be of any preferred construction, preferably, however, consisting, essentially, of a base and suitable uprights, as shown in the drawings, the bottom plate A being provided, upon which the various parts of the mechanism are mounted, as Will hereinafter appear. At the top the frame A is provided with tracks or ways in which are mounted anti-friction rollers A each provided with V-shaped peripheral grooves, on which rollers the rails B of the paper-carriage are supported. The carriage proper consists, essentially, of a rectangular frame, of which the rails B B form the longer sides and the pieces B 3 the ends. Each of the rails B B is provided on the under side with a V-shaped projection or rib,

which co-operatcs with the corresponding groove in the anti-friction rollers A and besides serving as the supports for the carriage, the rails also serve to hold the carriage securely in place against upward movement, being embraced by the upwardly-extending and overhanging projections A at front and rear of the main frame.

Any preferred mechanism for feeding the carriage may be employed, although the structure shown is preferred, and is'adapted for use in connection with the feeding mechanism embodied in my application, Serial No. 347,627, filed April 12, 18.90.

Referring particularly to Fig. 2, it will be seen that a wheel 0, consisting, essentially, of two segmental sections, the lower one provided with ratchet-teeth, with which the feeding-pawls-engage, and the upper one jointed to the carriage by means of flexible bands 0, the opposite ends of which are connected, respectively, to the opposite ends of the carriage and segment, is employed to form a connection between the feed mechanism and carriage. This wheel 0 is mounted on a central pivot 0 to which one end of a coilspring 0 is connected, the opposite end being connected to an adjustable drum C the tendency of the spring being to rotatethe I wheel in a direction to feed the carriage forward. The drum is adjusted and held in position by means of a handle 0, which may be connected to any one of the series of projections 0' by. a pin 0 as shown in Fig. 2, or other well-known connection and is itself adj usted to change the tension of the spring within very narrow limits by being put in engagement with any one of theseries of stopteeth a on the bar 0 affixed to the frame A. In the preferred construction the carriage is returned to first position by means of a cord D, connected at one end to a grooved segment 0 on the wheel 0, passing around a pulley e on the frame at the right-hand end of the carriage and connected to the rear end of a long lever D, pivoted at the front of the machine at the right-hand end. This lever is elevated by means of a spring D and depressed to return the carriage and feed the paper by means of an angle-lever D the upper armof which constitutes a finger-piece when the carriage is returned by hand or as a connection for the foot-treadle cord when the carriage is returned by foot-power, and the lower arm of which is bifurcated and engages the lever D, as shown clearly in Figs. 1 and 2, an anti-friction roller 01' being provided to contact with said lever. A guide at is secured to the frame for keeping the lovers D D in their proper relative positions.

Within the rectangular carriage-frame before mentioned is pivoted on centers formed by a stud-axle 6 what may be termed a supplemental or platen frame composed of the side pieces E and the connecting-piece E, which passes along at the backof thevplaten F and by which the side pieces are caused to move in unison. Forward of the stud-axle e the side pieces E are provided with bearings, 4 in which the pivots F of the platen F are mounted, and the right-hand piece E is further provided at the front with an upward extension E for a-purpose to be presently explained. The platen, it will thus be seen,

is journaled in the supplemental frame and turns therein to feed the paper forward; but

whenit is desired to expose the printing-point the supplemental frame is turned up, carr ing the platen, paper-guides, and feed-levers out of contact with the ribbon, a quarter-turn being sufficient to bring the printing-point up into View and to throw the center of gravity back of the pivotal point, if desired,

thereby keeping the platen-elevated When brought forward of the center, gravity at once asserts itself and the platen is returned to normal position; but the pivotal point of the supplemental frame is such a very slight distance in rear of the platen center that the weight of the platen and connected parts forward of said center is counterbalanced in a large measure by the weight of the parts in rear of said center, causing the supplemental frame to turn up with the application of u but very little force.

The supplemental frame is turned by means of a finger-piece E attached to the rearwardly-extendi-ng portion of the righthand piece E, which finger-piece is provided with a notch E and spring E for engagement with the carriage-frame to hold the platen locked down in printing position. At the right-hand end the platen is provided with a serrated wheel f,

with which a serrated block f 'on a spring f mounted on the piece E, engages-to lock the platen and supplemental frame together.

The paper-guide, consisting,essentially, of a wide sheet-metal case G, at the rear connected to the spring-arms G on the supplemental frame, terminates in front in two spring-arms G which pass up around the platen at each end and hold the paper firmly in contact therewith. .To each of these spring-arms is attached one end of the spring-wire paperguide in front of the platen, the lower end of thecenter piece g of which is adapted to be depressed below the center of the platen to catch j the edge of the paper as it is inserted, as will be readily understood from an inspection of Fig. 4.

The paper-feed lever H is pivoted on a link H, journaled in the platen-center, and Works in the space between the horizontal projections hon the extension E and its movement is regulated to vary the extent of papenfeed by means of the stop 72.3, which consists simply of a piece of steel bent into the shape shown and working on the notched pin h extending between the two projections, and having a spring h with one end bent in to engage said notches and the other extended out into the path of the lever. By adjusting the position of the stop it will thus be seen that the distance the lever can move is correspondingly varied.

1 with the ratchet-wheel f to permit the platen to rotate independently, it may be accomplished by pressing the thumb-piece H connected to the spring-lockf, backward, the feed-lever H being simultaneously elevated by means of the link H the hooked end of which passes beneath the same.

For the purpose of automatically feeding the paper forward as the carriage is returned to first position the paper-feed lever is provided with a hinged rearward extension H, with which the end of the upwardly-extending projection You a spring-support I is adapted to engage. This projection 1 is mounted on one of the bifurcated ends of a spring-support I, secured rigidly to the left-hand end of the carriage in rear of the rail B. The other arm 1 of the spring-support is somewhat elongated and when the carriage is returned to first position passes beneath an anti-friction roller 2' on the upper end of a rod t", which is pivoted to the end of a spring-support 7?, secured rigidly to the left-hand frame of the machine, said spring-support being very similar to the spring-support I on the carriage, save that it is somewhat larger, and the rod 1" is held in upright position by a spring m unted rigidly on the support 1?. The end of the lever D passes down inside of the rod 1'', and as it nears the end of its downward movement of course comes in contact w ith the end of the support 2' and carries it, together with the spring-support I, extension I, and rear end of the papenfeed lever, down with it. By bifurcating the end of the support I it will be seen that the rod t" is permitted to engage and remain in engagement therewith until the carriage has traveled far enough to cause a complete downward movement of the rear end of the paper-feed lever, the anti-friction roller t' being adapted to roll along the support as the carriage returns, \Vithout the bifurcated end provision would have to be made to permit the roller t'to pass the extension 1'. Any slight variation in the extent of throw of the paperfeed lever or movement of the carriage is compensated for by thelateral swing of the rod 2". In returning the carriage by foot-power, and, in fact, under all circumstances, it is highly desirable that a solid stop shall be provided for arresting the same, and in my present construction I employ the stop K, having a series of steps thereon, any one of which may be brought into line with the segment of the wheel by manipulating the set-screw K, as will be readilyunderstood. To indicate when the platen has reached the extreme of its movement in the other direction, a bell 7c is fixed at the left-hand side of the frame in rear thereof, and a bell-hammer it" (see Figs. 2 and 5) is pivoted on the axle of the wheel 0 and adapt-ed to be thrown against the bell at the proper' 'moment by an adjustable stop 7& on one of the spokes or radial arms of the wheel, said hammer being returned to normal position at the right of its center of gravity by thepin Ye The ink-ribbon in the present instance is mounted directly on the carriage and is adapted to travel with the same, mechanism for giving the ribbon a single movement longitudinally and also a single movement laterally at each reciprocation of the carriage being provided, as follows: Beneath each of the end pieces B are secured hanging supports L, (shown clearly in dotted lines in Fig. 1 and in full lines, Figs. 7 and 8,) on which supports theink-ribbon carriages L are mounted. These carriages have two spring-armsL projecting out horizontally from each end of the paper-carriage and between which the inkribbon spool is held, said spool having small projecting trunnions or the equivalent thereof, which engage bearings in the said arms, the ob jeet being to provide a means whereby the spools having the ribbon thereon may be easily slipped into position or removed, as 00 casion demands, by springing the arms apart.

The ink-ribbon carriages are adapted to slide on the hanging supports L, the portion of said carriages which comes in contact with the under face of the end piece B serving to prevent the same from sagging down at the outer end, and in order to impart to said carriages the desired reciprocation two wheels M M, one of which is grooved, are mounted on opposite ends of a common shaft M, journaled in the paper-carriage, the wheels being provided on their outerfaces with crank-pins m, which are connected to the ink-ribbon carriages by connecting-rods m. Thus as the wheels are rotated step by step, as will now be described, the ink-ribbon is reciprocated toward front and rear of the machine to present fresh surfaces for the action of the types, the extent of such movement being regulated of course by the throw of the crank-pins m. At the front of the support L an arm M is pivoted, which extends toward the rear of the machine and beneath the wheel M, a small coil-spring M being attached to said arm in front of the wheel, passed over the same in the groove thereof, and its other end connected to the arm M at the opposite side of the wheel. The end of the arm M projects into proximityto the rear portion of the frame A, and on the latter is pivoted a pawl M adapted to be struck by the end of the arm M and swung up against the stop M in which position it forms an incline, down which the arm travels, causing the rear end of the spring to be elongated and the wheel M rotated toward the rear. Actual practice demonstrates that said wheel will not return to to its original position when the spring is released suddenly from the end of the pawl. On the return movement of the carriage the pawl is thrown up in the opposite direction and permits the arm to pass without obstruction. I

To give the ink-ribbon longitudinal movement, the flange at one end of the same is made too roq

IIO

in the form of a toothed wheel m which is adapted to come in contact with an elongated pawl m affixed to the framebeneath the papercarriage. Thus as the carriage is moved along the ways the toothed wheel strikes against the pawl and is rotated the distance of a single tooth, the pawl being permitted to swing on the return movement, and thereby prevent the backward movement or" the ribbon.

The pawl M it will be observed, is long enough to engage the wheel M at any point of its movement toward the front and back of the machine, and with the construction shown by reversing the position of the pawl M the direction of movement of the ribbon may be reversed, a small set-screw being provided for adjusting the angular position of the pawl, so as to determine the extent of movement of the wheel m As a feature of the presentmachine, I have designed a mechanism for indicating when rear of the platen and pivoted to a downward extension n thereon is a light spring-lever N, the lower end of which projects in proximity to the wheelN just forward of the paperguide and below the platen and the rear end of which carries a small bell N andis adapted when elevated to come in contact with the end of a strike-arm N 'or equivalent 011 the frame of the machine, preferably at one end.

The operation is as follows: When the paper is inserted or passed around the platen, it

bends the radial arms at inward, where they I cannot come in contact with the end of lever N; but as soon as the paper has passed beyond the rear guide the radial arms spring outward and elevate the rear end. of the said lever N, and when the carriage is brought back to first position it strikes the stop-arm and rings the bell, indicating to the operator that the end of the sheet has been reached.

One of the objects of the presentinvention is to provide a machine in which the power shall be applied to the type-arms in aline coincident with its direction of movement or in its-plane of movement, whereby the pressure applied to its pivots shall be exactly equal, thereby maintaining the alignment of the printing even though the pivot should become 'very much worn and the wear and friction on each pivot equalized, to accomplish which the followingmechanismis employed Thehangerrail 0 or portion of the frame in which the type-arms are pivoted is in the preferred construction provided with a series of slots corresponding in number to the number of typearms employed, and in the outer side of said hanger-rail is formed a circumferential recess or groove 0 for the reception of the pivots 0 of the type-arms P, by which construction it type-arms may be compensated for by wedging said bifurcated ends apart, as will be readily understood. 7 t

The pivotal ends of the type-arms are preferably formed substantially circular, as shown in Figs. 10, 11, and 13, and provided with a gear-segment p on the under side, with which gears a corresponding segment 19 on the upper end of the levers p pivoted to a centralbearing extending around the type-basket.

The key-levers are arranged in rows, as in the ordinary machinesnow in common use, and are in the form of angle or bell-crank levers Q, as shown in Figs. 1 and 12, each row being pivoted on an independent cross-rod, and it will be seen that in order to operate the typearms at the front, of the machine it is only necessary to connect the lower ends of the levers p with the upwardly-extending arm of the key-levers by means of a fine wire q or other suitable connection; but in order to make the connection with the levers p at the rear of the type-basket it is necessary to employ an intermediate reversing-lever 19 Fig. 13, to' the lower end of which the wire connection with the key-lever is attached, the wires q extending to the levers at the back of the type-basket, preferably all across at the center of the type-basket, so as to give a direct pull on the type-arm-operating levers, as will be readily understood.

At the sides of the type-basket bell-crank levers R are preferably employed, as shown in Fig. 14, for making the connection with the lower ends of the type-arm-operating levers, which connection may be direct, as shown, the lower ends of said levers being deflected into position for engagement with the bellcrank levers, as shown in Fig. 16, to prevent any interference with each other. If desired, the bell-crank levers for the rear portion of the side section of thebasket may be mounted on the same pivot, as shown in Figs. 14 and 15.

In lieu of the arrangements just described for operating the type-arm levers, the one shown in Figs. 21 and 2% may be employed, wherein it will be seen that the lovers p are pivoted at the bottom on a shaft S, mounted in bearings on the base-plate and connected by a universal joint S with a shaft S eX- tending forward beneath the key-board and having on its forward end along arm S which passes beneath a key-lever at the opposite side of the key-board. With this arrangement the angle at which the lever 11 shall be made to operate can be varied indefinitely, and by the employment of the small rotary shafts the keys may be multiplied almost indefinitely without interfering with each other in the least.

Referring to Fig. 12, 3 indicates the rod for operating the feed mechanism of the papercarriage, and s is a pivoted lever carrying at the top a slotted cross-piece 8 through which the rods 8 connected to the key-levers, pass. Said rods 8 are provided on the rear of said cross-bar with collars s, and as any one of the key-levers are depressed it draws the bar forward, operating the feed mechanism, the bars connected to the remaining key-levers offering no obstruction to the forward movement of the bar by reason of the slot aforesaid.

In order to prevent the operation of but one key-lever at a time, the bars 5 are extended and curved into the form shown in Fig. 12, their forward ends projecting just within' a slot in the tube T, mounted in rear of the lever .9. The tube T has within it a series of balls i, one for each rod, and between these balls the rods are adapted to pass, sufficient space, however, being left between the whole series of balls for the passage of but a single rod. Hence it will be seen that when one of the key-levers is operated the space is taken up and none of the others can enter.

The type-ar1ns may be accurately aligned by means of the aligner-strips t, which are secured to the hanger-rail and adapted to engage the circular rear end of the type-arms, as shown in Figs. 10 and 11, the ends of said aligner-strips being bifurcated or provided with a V-shaped recess, which embraces said circular end, the latter being preferably correspondingly shaped, as shown.

To facilitate the retu rn of the paper-carriage to first position, the cord U is attached to the hand-lever D and extends down and is connected to the outer end of a lever U, pivoted to a base U The base U is provided with bearings U at each side of said lever, and in these bearings a frame U is adaptedto slide, the top surface of said frame being suitably formed for foot-rests, as shown in Fig. 24. The inner end of the lever U is made in the form of a gear-segment U adapted to gear with a rack-segment U on the under surface of the frame U, whereby when the frame U is pushed forward by the operator the lever U is depressed and the carriage returned to position. A spring U is employed to return the frame U to first position again. The advantage of this construction of foot-power mechanism lies in the fact that the feet of the operator may remain at all times substantially horizontal, thereby relieving him of the strain incident to keeping the toes elevated, as would be necessary if a pivoted footpiece were employed.

For use in connection with the present machine and, if desired, in connection with other machines of this class I have designeda motor for aiding the operator in depressing the key-levers, the object being to increase the speed of the machine, and the gist of this feature of the invention may be said to consist in providing a motor beneath the keyboard. with which any one of the key-levers may be connected by a very slight depression of the same. Thus it is only necessary for the operator to depress the desired key a very short distance when the motor engages therewith and causes the further depression, the connection with the motor preferably being broken as soon as the impression is made. Further, the invention may be said to consist in making a magnetic connection between the key-levers and motor, suitable magnets being mounted on the motor to move therewlth, and a co-operating armature on the key-levers.

Referring particularly to Figs. 17 to 20 of the drawings, it will be seen that a stand or table 2 is provided for the type-writer, in the top of which is mounted a frame 3, carrying a series of magnets t, which work through orifices provided in a plate 5, forming the portion of the table-top lying immediately beneath the keyboard. The frame 3 may be mounted in any suitable manner, preferably, however, in bearings 0 6, and connected by pitman 7 with the crank-shaft 8, driven by any suitable power applied to a pulley 9. Suspended from each of the key-levers is an armature 10, having its lower face somewhat larger than the magnet with which it is adapted to contact, as shown in Fig. 19.

The operation is as follows: The frame 3 and magnets are reciprocated, as before explained, the limit of the upward movement of the face of the magnet being just below the point at which they would attract and hold the armatures 10 on the key-levers, and when the operator depresses any particular keylever it is seen that the armature is brought near to the magnet and is attracted thereto and carried down with the motor, the connections between the magnet and armature being broken by the armature coming to rest on the stop-plate 5, while the magnet continues to move downward a suflicient distance to allow the key-lever to return to normal position under the influence of the ordinary spring-returning devices.
